I dont know about your experience on Windows 10 ,
but I love it!
It is a fusion of Modern Metro UI plus the "old" Win 7 menu that makes me like it. Unlike Win 8 which forces you to use MetroUI.And this brings me to this issues with after market menu apps. I made a big fuss on IO Bit Start Menu add-on that comes free with Advanced System Care 8 before. With Win10 you dont have to have add-ons like this. My experience with IO Start Menu was that oonce it is installed it completely disable the Metro UI on Win10 (it was meant for Win8.1 but they advertise it as being Win10 "compatible")and even after uninstalling the app you can never be able to use Metro UI. That caught the attention of IO Bit and they promptly did an upgrade of their app but I never want to install ever again.
Therefore dont install any add on app to Win10 for start menu as it will disable your Modern UI and even your Win Store app. But IF you happen to lose your use of Modern UI due to other reasons (other than installing start menu modification app), there is solution for it.As I had on many occasion unable to acccess Modern UI after an "update" from MS or installing an app that causes a corruption of certain links and files (I dont know which ones)
1. Install it on your PC and Follow the instructions to reboot into "SAFE MODE" (the app will do it for you)
2. Go through the Steps by step analysis and repair (done by the app)
3. Finally after going through the steps and "REPAIR" and then set it to reboot automatically.
4. DONE!
The whole process might take up from 30minutes to 45minutes but the end result is a spanking new feel to your PC. Warning : Do Not run this app when your PC doesnt have any problems! There are cases where it might cause damage to your PC. If you dont have backup then it is your fault.
A NOTE OF CAUTION - ALWAYS DO A BACKUP OF YOUR PC WHEN IT IS STILL NEW AND TROUBLE FREE. IF AFTER THIS REPAIR YOUR PC WORKS WELL IMMEDIATELY DO A BACKUP.
For those that has truble on their Win10 PC , please check whether you have the updated version of Win10 1511. If you DO NOT HAVE the 1511 update or always fails to update to the latest version of which is Win10 1511 March release. Please download the full ISO for that version and update. This is will give you are more stable Win10 versionwith new start menu and faster PC boot up.
